7.4.2 Dual card set redundancy
Dual card set redundancy is shown in Figure 27: Ring topology; Dual card set redundancy ,
with both Card set A and Card set B fitted in each node of the ring. In this case each matrix
contains two Fiber-optic Linking card sets.
This approach affords full redundancy, offering protection against component failure within a
single Fiber-optic Linking Card Set
Note:
In the absence of an Uninterrupted Power Supply this configuration will not protect against
loss of the node or Matrix Frame itself.
